Just to clarify, I don't really consider my position to be eliminative towards green, only that what we are talking about when we talk about green 'qualia' is nothing more than a certain type of sentient experience. This may eliminate what you think you are talking about what you say green, but not what I think I am talking about when I say green. I am willing to say that the part of a functional pattern of neural activity that is experienced as green qualia is identical to green in the sense that people generally mean when they talk about seeing something green. But there is no way to separate the green from the experience of seeing green.

Do you think that green is something separate from or independent of the experience of seeing green? Do you believe that seeing green is some sort of causal relationship between 'green' and a conscious mind similar to what a content externalist believes about the relationship between intentional states and external content? I don't understand why you believe so strongly that green has to be something beyond a conscious experience.

ETA: For a position that I believe to be more extreme/eliminativist than mine, see Frank Jackson's paper Mind and Illusion, where he argues that seeing red is being in a representational state that represents something non-physical(and also not real), in the same way that someone could be in a representational state representing a fairy.

From that paper:

Intensionalism means that no amount of tub-thumping assertion by dualists (including by me in the past) that the redness of seeing red cannot be accommodated in the austere physicalist picture carries any weight. That striking feature is a feature of how things are being represented to be, and if, as claimed by the tub thumpers, it is transparently a feature that has no place in the physicalist picture, what follows is that physicalists should deny that anything has that striking feature. And this is no argument against physicalism. Physicalists can allow that people are sometimes in states that represent that things have a non-physical property. Examples are people who believe that there are fairies. What physicalists must deny is that such properties are instantiated.

I think he is basically saying that if you can imagine the concept of something that isn't physically real (like a fairy), why couldn't you have a state representing redness, even though redness is not physically real? Or, for an example involving something ontologically unreal, one could have beliefs about the vitalist's élan vital even though it is not made of any ontological entities from the physical universe, so why not have conscious states about red even though it has no place in physical ontology. I'm not sure I agree with his belief that colors can't be considered to have physical ontology, but he seems to agree with you on that point.

I would essentially deny that anything is actually green, but assert that there is a mental state of "experiencing green", which is a certain functional state of a mind. You say that reductionists believe "...the green shape that you are seeing is the same thing as some aspect of all those billions of colorless atoms in motion." I do not think that most reductionsts would (or should) take this position. There is nothing "the same" in the mental state of experiencing green as in the green object, there is only some property of the green object that causes us to have a green experience. My response to "If your theory still makes sense to you, then please tell us in comments what aspect of the atoms in motion is actually green." is that the atoms in motion comprise a mental state which is the experience of seeing green, and that this is all there is to our idea of the color green. Certainly, no aspect of the green object itself is identical to any brain state. So, I deny the existence of any such thing "green" which is both a property of green objects and a mental state, but claim that what we are talking about when we say we see green is nothing more than a mental state.

I posted the following about a JJC Smart quote on the issue in your last thread, but I'll repost it here in case you didn't see:

JJC Smart responds to people who would conflate experiences of seeing things with the actual things which are being seen in his 1959 paper "Sensations and Brain Processes". Here he's talking about the experience of seeing a yellow-green after image, and responding to objections to his theory that experiences can be equivalent to mental states.

Objection 4. The after-image is not in physical space. The brain-process is. So the after-image is not a brain-process.

Reply. This is an ignoratio elenchi. I am not arguing that the after-image is a brain-process, but that the experience of having an after-image is a brain-process. It is the experience which is reported in the introspective report. Similarly, if it is objected that the after-image is yellowy-orange but that a surgeon looking into your brain would see nothing yellowy-orange, my reply is that it is the experience of seeing yellowy-orange that is being described, and this experience is not a yellowy-orange something. So to say that a brain-process cannot be yellowy-orange is not to say that a brain-process cannot in fact be the experience of having a yellowy-orange after-image. There is, in a sense,no such thing as an after-image or a sense-datum, though there is such a thing as the experience of having an image, and this experience is described indirectly in material object language, not in phenomenal language, for there is no such thing. We describe the experience by saying, in effect, that it is like the experience we have when, for example, we really see a yellowy-orange patch on the wall. Trees and wallpaper can be green, but not the experience of seeing or imagining a tree or wallpaper. (Or if they are described as green or yellow this can only be in a derived sense.)

The theory he is defending in the paper is an identity theory where brain states are identical to mental states, but the point still holds for functionalist theories where mental states supervene on functional states.

You constantly elide between the property of being green and the experience of something green. Which leads to the ancient mistake of saying that whatever constitutes your experience of something green must itself be green. Admittedly you put this enormous red herring in the mouth of your opponent, but it's totally unwarranted nonetheless.

e.g.

Such a theory will necessarily present a candidate, however vague, for the physical correlate of an experience of color. One can then say that color exists without having to add anything to physics, because the color just is the proposed physical correlate.

The happy materialist might say: but those aren't the things which are truly green in the sense you care about; the things which are green are parts of experiences, not the external objects.

You also then essentially just say "But qualia! Intentionality! They're so real! There must be something more!", i.e. the same argument dualists have been making since the dawn of time, and that any attempts to dissolve the question have failed, since

all you have to do is attend for a moment to experience itself, and then to compare that to the picture of billions of colorless atoms in intricate motion through space, to realize that this is still dualism.

Furthermore, all the arguements you use are pretty much applicable across the board, and don't particularly relate to functionalism, so I think it's disingenuous of you to say that you're arguing for "functionalism implies dualism" rather than simply "dualism is true".

Downvoted.

If you didn't put a colon between 0 and return, it's invalid syntax.

Greater than signs are only necessary at the beginning of the paragraph, by the way.

Unlike statements of fact, which require no further work on our part, lies must be continually protected from collisions with reality. When you tell the truth, you have nothing to keep track of. The world itself becomes your memory, and if questions arise, you can always point others back to it. You can even reconsider certain facts and honestly change your views. And you can openly discuss your confusion, conflicts, and doubts with all comers. In this way, a commitment to the truth is naturally purifying of error.

if you think of future versions of yourself as separate agents, then suicide is a form of homicide.

It seems like that argument also implies that failing to bring into existence as many people as possible is comprable to homicide, since doing so would be depriving potential people of their lives. So, if you don't believe it's a moral responsibility to create more people, you shouldn't accept the argument that suicide is a crime against your future self either.

A related anecdote: A few years ago, I asked my friend, a neuroscientist specializing in vision, why it's sometimes painful to look at the sky. After confirming that it's unrelated to cloud cover but vaguely correlated with the seasons, he suggested that it might be that I'm sensitive to the polarization of light, but said that this was unlikely since mammals in general are supposedly not capable of detecting it. Polarized glasses are cheap, though, so I tried them, and they entirely fixed the problem - notably, regular sunglasses do not - indicating that that is probably the case.

Even more interestingly, I discovered that some significant parts of my visual experience were related to polarization: Detecting the rotation of distant reflective objects (panes of glass, leaves) is helped by it, for one. More significantly, perceiving how far away objects are is affected by it: It's easier for me to tell how far away a small, relatively still object is without the glasses, but also much easier for me to tell how fast a large object is approaching with them, and I find crossing busy roads to be much less stressful that way. I also find certain kinds of reflective surfaces confusing with the glasses, but entirely sensible without them.

The human eye is slightly sensitive to the polarization of light. See Haidinger's brush, which is a yellowish bowtie shaped pattern some people can see in the center of their visual field when looking at the sky while facing away from the sun.
